Relatively recent descriptions of development exist for the teleost fishes, bowfin, sturgeon, paddlefish and bichirs. Such literature dealing with the gars is to be found in older work, done approximately a century ago. The present study concerns the gars, of which the garpike, Lepisosteus osseus, is a representative by: Image Scientific name Common name Distribution Lepisosteus oculatus Winchell Spotted gar: North America Lepisosteus osseus Linnaeus Longnose gar: east coast of North and Central America in freshwater lakes and as far west as Kansas and Texas and southern New MexicoClass: Osteichthyes. In the spring of I journeyed to North America for the purpose of collecting material for a study of Ganoid development. I sought and found even more material than I wanted in the now well-known habitat of Lepidosteus, Black Lake, N. better hunting-ground could be wished for by the morphologist in search of Ganoid material.

The Longnose Gar, Lepisosteus osseus, is a member of the basal actinopterygian family Lepisosteidae. are organized more simply early in development, making comparisons and homology assessments. The present study of Lepisosteus osseus dimorphism expands upon previous work by examining a broader array of morphometric characters while removing the bias associated with overall body length. Fast-starts and steady swimming were compared for two piscivorous fishes, the longnose gar (Lepisosteus osseus), which has an integument armored with ganoid scales, and the unarmored tiger musky (Esox sp.).The body was similarly flexed by both species during fast-starts and steady swimming.

Lepisosteus osseus specimens larger than 6 inches are not likely to be confused with L. platostomus (shortnose gar) and L. octulatus (spotted gar); L. osseus can be distinguished from the latter two species by the extremely long snout (versus much shorter, wider snouts; Hubbs et al. ; Page and Burr ; Etnier and Starnes ).

Gar eggs are highly toxic to humans. Members of the gar family have been present in North America for about million years. Identification. Early development of Lepisosteus osseus.
